Last year people came together at BrickWorld to make a "Journey of the Fellowship" display. I'll try and get all of those posted, here. Let's start with a look at Dave Kaleta's great Rivendell.
Quick note - I'm using the tag for Fellowship here rather than Hobbit. Yes, this location first shows up in the Hobbit, but the description there is really sparse. Plus this particular setup does have figures there from Fellowship, though I've focused more on the location shots than the figs in them.
